Изобретение относитс  к устройствам дл  очистки поверхностей нагрева от наружных отлсзжений, например труб конвективных пакетов, размещенньк в газоходах котлов, и может найти применение в теплоэнергетике, цветной и черной металлургии .The invention relates to devices for cleaning heating surfaces from external surfaces, such as pipes of convective bags, located in boiler ducts, and can be used in power engineering, non-ferrous and ferrous metallurgy.

Известно устройство дл  очистки от наружных: отложений труб конвективньк пакетов, содержащее очистной инструмент и привод дл  возвратно-поступательного движени  его в направлении .вдоль оси труб 1.A device is known for cleaning from external: deposits of pipes of a convective bag containing a cleaning tool and a drive for reciprocating it in the direction along the axis of the pipes 1.

Однако устройство имеет низкие эффективность и степень очистки труб.However, the device has low efficiency and degree of cleaning pipes.

Цель изобретени  - повышение степени очистки.The purpose of the invention is to increase the degree of purification.

Это достигаетс  тем, что очиьтной инструмент вьтолнен в виде набора гибких длинномерных металлических элементов , установленаьрс попарно в каждом р ду очищаемых труб и охватьшающих их, при этом металлические элементы вьтолнены в виде цопсй.This is achieved by the fact that the cleaning tool is complete in the form of a set of flexible, long metal elements, installed in pairs in each row of pipes to be cleaned and covering them, while the metal elements are made in the form of cords.

На фиг. 1 показано предлагаемое устройство , фронтальна  проекци ; на фиг. 2 - сечение А-А на фиг. 1; на фиг. 3 вариант выполнени  очистных элементов в виде цепей.FIG. 1 shows the proposed device, frontal projection; in fig. 2 is a section A-A in FIG. one; in fig. 3 embodiment of the cleaning elements in the form of chains.

Устройство состоит из рамы 1, размещенной в промежутке 2 трубных пакетов 3, к котсрой присоединен одним каК ii. очистной иструмент 4. Рама 1 соединена штангой 5 с приводом возврат10 но-поступательного движени  (на чертеже не показан), размещенным с наружной стороны газохода. Дл  предупреждени  перекосов при движении рамы 1 с очистными инструментами 4 служат упоts ры 6. Очистной инструмент может быть бьшолнен в виде цепей 7,The device consists of a frame 1, placed in the interval of 2 tube packs 3, attached to it as one as ii. cleaning tool 4. The frame 1 is connected by a rod 5 to a drive for returning 10 a translational motion (not shown) located on the outer side of the duct. To prevent distortions in the movement of the frame 1 with the cleaning tools 4 serve as stops 6. The cleaning tool can be filled in the form of chains 7,

Устройство работает следующим образом . При включении привода штанга 5 перемещает раму 1 вдоль труб пакетов 3 The device works as follows. When you turn on the drive rod 5 moves the frame 1 along the pipe package 3

20 вместе с очистными инструментами 4, набранными в два р да, один из которых механически разрушает отложени  с левой , по ходу движени , стороны трубы. а второй - с правой. При этом трубы очищаютс  по периметру и по длине. Дл  более полного удалени  отложений край очистного элемента снабжен режущей . кромкой. При наличии на очищаемьк тру бах неровностей целесообразно вьтолнит очистной инструмент из цепей 7. В нерабочем положении устройство расположено в пристенной зоне конвективного Газохода и не нарушает аэродинамической структуры газохода. Формула изобретени  1. Устройство дл  очистки от наружных отложений труб конвективных цаке7 З4 тов, содержащее очистной инструмент и привод дл  возвратно-поступательного его движени  в направлении вдоль оси труб, отличающее с  тем, что, с целью повьплени  степени очистки, очистной инструмент вьшолнен в виде набора гибких длинномерных металлических элементов, установленных попарно в каждом р ду очищаемых труб и охватывающих их. 20 together with cleaning tools 4, assembled in two rows, one of which mechanically destroys deposits on the left side of the pipe as it moves. and the second - from the right. In doing so, the pipes are cleaned around the perimeter and length. To more fully remove deposits, the edge of the cleaning element is provided with a cutting. by edge. If irregularities are present in the cleaning pipes, it is advisable to make a cleaning tool from chains 7. In the off position, the device is located in the near-wall zone of the convective Flue and does not break the aerodynamic structure of the flue. Apparatus of the invention 1. A device for cleaning of external deposits of convective piping tubes of 3 to 3 pipes, comprising a cleaning tool and a drive for reciprocating its movement in the direction along the axis of the pipes, which, in order to increase the degree of cleaning, a set of flexible long metal elements installed in pairs in each row of pipes to be cleaned and covering them. 2. Устройство по п. 1, отличающеес  тем,, что металлические элементы вьтрлнены в виде цепей. Источники информации, прин тые во внимание при экспертизе 1.
